the-inclined magazine, fromtheLlower end 1 To all whom it may concern of the borough of ,Brooklyn,: county of Kings, and State 0f,New.,York, have invented a new and useful Im rovement in Line- Gasting Machines of W ich the following 1s a specification.

My invention has reference to line casting machines of the Mergenthaler type, wherein matrices released one at atime from amagazine descend through vertical guides to the carried downward, and delivered successively into a channeled assembler, in which side by side,

they are assembled-or composed side by side in a common line. In the modern machines speedy substitution of-one font of matrices for another. Matrices of different fonts, and sometimes matrices of the same font,

and it is found that the thick and heavy objectionable velocity and violence to their position at the end of the hire, the effect being to disturb the line, and also to injure the preceding matrix.

The object of my invention is to overcome this difficulty by the provision of a yielding guide or resistant of such character that while all matrices are permitted-to descend freely to the line, the thicker matrices are subjected, in advance of the line, to a re-. tarding or resisting influence automatically variable in proportion to theweight of the matrices. To this end I employ a yielding resistant overlying the path of the descending matrices in advance of "the point at which the matrices are assembled. In its preferred form this resistant consists of two or more superpased springs, fixed at their upper ends, and having their lower ends in position to .contact with the matrices.

In the drawings I have shown my improvement applied to a commercial Mergenthaler linotype machine of the present day which may be inv all other respects of the ordinary construction.

In the drawings: Fi 'ure l is a front elevation of the composing mechanism having my improvement incorporated therein. Fig. 2 is a perspective view showing the resistant detached from the other parts. Fig. 3 is a cross-section on the line 3-3 of Fig. 1..

Referring to the drawings, A represents of which the ered one at-a time by and finger'key mechanism cally channeled face-plate through which these matrices descend by gr vity.

0 IS the inclined, season. y rotatingbelt on which the matrices are received, and by which they are carried downward to the left, over the stationary support D, into position in front of the star wheel E, by whlch they are urged rearward and downward into the upper, channeled end of the assembler F. he matrices are thus delivered successively,

into the assembler, and arranged thereinin a common line.

All the foregoing parts may be of the ordinary construction. In: carrying my invention. into effect I provide a spring resistant, Gr, and fix the same in position over the lower end of the assembler belt,'or over the stationary surface on which the matrices travel. This re sistant consists of a series of springs, g, 9, etc, having their upper ends separated by intermediate plates 9 and secured rigidly in position by screws 9, which pass through the springs and the plates into a stationary supporting bracket, The lower ends of the springs, which are highly flexible, overlie the path of the matrices, each spring preferably extended downward beyond the one beneath it so as to terminate at different distances from the point of composition. Each spring terminates at a point nearer the matrix-supporting surface than the one above. As a result of this arrangement the, springs will act individually or cumulatively in resisting the passage of the matrices according to the thickness of the latter. v v

Thin matrices descending toward the as sembler will entirely escape the springs, or will be acted upon only by the innermost, or lowermost, spring. Matrices somewhat thicker'will lift the first spring, and will be acted upon thereby, and also by the sec-- ond spring, While the thicker matrices will be acted upon by three springs-and so on successively-very heavy, thick, matrices J...

meeting the resistance of all the springs. In this manner the rapidly moving matrices are subjected to resistance in proportion to their Weight and momentum, and a sufliciently rapidrate of deiivery to the assem tea Nov. 25,1913.

Having described my invention, what I claim is e 1. In a mechanism of the class described, a-matrix retarding device comprising a plurality of springs, fixed at one end, and hav ing their free ends terminating at different distances from the. 'oint of composition so as to act individua 1y or cumulatively in resisting the passage of the matrices, according to the thickness of the latter. I

In a mechanism of the class described,

rality a matrix retarding device comprising a pluof superposed springs overlying the matrix path, and adapted to act individually or cumulatively so asto' ofi'er varying,

resistance to the passing type or matricesi'n proportion to the thickness of the latter.

In testimony whereof I hereunto set my hand this twenty first day of October, 1910, .in the presence of two attesting witnesses.
